December 18, China's largest monomer capacity approved offshore wind power project - Longyuan Putian Nanri Island Offshore Wind Farm Phase I project the first batch of 7 wind turbines and grid-connected power generation.
Fujian Putian Nanri Island Offshore Wind Farm Phase I project is located in the northeast side of Nanri Island, offshore distance of 11 kilometers, 25 meters deep water, installed capacity of 400MW, to be installed 100 4MW wind turbine.
There are more islands and reefs in the South China Sea, which are geotechnical seabed geology with complicated construction conditions.
After thorough investigation, some of the seats in the weathered granite buried shallow and high compressive strength, the conventional pile foundation construction is difficult to implement, low efficiency problems.
To this end, Longyuan Power actively explored offshore wind power construction technology and successfully created the world's first non-transition section socketed single pile sinking construction and 'implantable' embedded rock single-pile construction.
During the installation of the unit, a single-leaf split installation was creatively proposed to solve the installation problem of static and static at sea, which not only filled the gap of offshore wind power installation in the complicated geological sea area along the southeast coast of China, but also created a single offshore wind turbine unit Vane lifting the precedent.
It is estimated that Putian Nanri Island offshore wind farm project is completed, the annual electricity up to 1.4 billion kwh, can replace 450,000 tons of standard coal, reduce carbon dioxide emissions of about 140 million tons, saving more than 400 million tons of water, It is of great significance to improve the regional energy structure and protect the ecological environment.
